Description |
Color centers in diamond have proven to be promising candidates for not only quantum computing but also for quantum sensing. Amongst the various color defects, nitrogen-vacancy centers (NV centers) could provide a platform for precision magnetometry allowing for nanoscale magnetic imaging with applications in brain imaging, magnetotatic bacteria, quantum materials, geomagnetic fields, and many others. In this talk I will give an overview of our research towards the development of an imaging tool, aka, the quantum diamond microscope. While NV centers are routinely used for measuring static magnetic fields in a wide field of view with diffraction limited spatial resolution, dynamic widefield magnetometry has been very challenging. I will describe the first demonstration of dynamic widefield magnetometry using Nitrogen vacancy centers in diamond and its applications.
